Introduction

Power relays provide electrically isolated switching solutions to control power, providing an interface between two circuits with different voltages. Over the years, the use of power relays has become latest widespread, mainly due to the arrival of digital electronics and electronic controls. Power relays can be used to control circuit boards, switches, and motors, as well as provide power where small amperage is required.

RT4S4LC4 Application Field and Working Principle

The RT4S4LC4 is a general-purpose power relay, rated at 2-4 A, 12VDC, with a single pole double throw (SPDT) CO configuration. It is an ideal application for automotive and industrial applications, as the wide switching voltage range and low power consumption make it a suitable choice for many applications. The RT4S4LC4 can be used for load control applications such as HVAC, lighting, motor control, and automation.

The RT4S4LC4 is designed to provide electrical isolation between one or more load circuits and a switched source(s). The relay provides high isolation between the input and output of the relay. It includes a high-quality contact construction ensures reliable switching of loads up to 4A with 12VDC. It also features a mechanical life of 10,000,000 operations and a contact resistance of 100mΩ.

The RT4S4LC4 is designed to be operated by a 12VDC power source connected across its two coil terminals. When the coil is energized, the SPDT switch is operated simultaneously with the internal switch contacts. When the coil is de-energized, the SPDT switch is then returned to its default position. The RT4S4LC4 is rated for a contact load up to 4A, 12Vdc, and AC voltage up to 250VAC. It has UL and CSA certifications, as well as an extended temperature range.

Conclusion

The RT4S4LC4 is an ideal power relay for controlling loads up to 4A with 12VDC. The versatility of the relay makes it suitable for many automotive and industrial applications, such as HVAC, lighting, motor control, and automation. It is rated for 10,000,000 operations mechanically, and has extended temperature range and UL/CSA certifications. For these reasons, the RT4S4LC4 is a great choice for power control applications.
